Celestron CPC 800 GPS XLT
This telescope requires a power supply - & you should consider a higher specification unit for accessories such as dew heaters. You can choose a mains or a portable solution (right). Lithium batteries are more expensive but out perform the lead acid options.
A reducer (below) will widen & brighten your field of view. Seeing more objects & the view is optimised for imaging (day & night).
The CPC 800 GPS XLT is the most portable of Celestron's top-of-the-line fork-mounted astronomical telescopes and includes Celestron's premium StarBright XLT coatings. This telescope is at home as a superb visual instrument or, with optional wedge and CCD cameras, as a serious astro photographer's tool.
Turn this scope to planets and see amazing detail on the surface of Jupiter; see Cassini's Division in the rings of Saturn, and resolve details on the surface of Mars. Even the distant Uranus, Neptune and Pluto are within your reach.
Although large in aperture, with its conveniently located carrying handles and an instrument weight of only 42 lb., this telescope is portable enough to setup in your backyard or take with you to your favorite dark sky location.
Celestron's new CPC Series with revolutionary SkyAlign Alignment
Technology re-defines everything that amateur astronomers are looking for — quick and simple alignment, GPS, unsurpassed optical quality, ease of set-up and use, ergonomics, enhanced computerization and, most important, affordability.
The CPC Series' internal GPS receiver automatically downloads the date and time from orbiting satellites and pinpoints its exact location on Earth. This eliminates the need for you to manually enter the date, time, longitude and latitude.
Celestron's Revolutionary SkyAlign
Once the CPC's internal GPS has established the telescope's position, aligning the telescope is as easy as 1-2-3! Simply locate and use hand control to manually point (slew) the telescope to three bright celestial objects. You do not need to know the names of the stars — you may even pick the moon or bright planets! Celestron's NexStar® software technology will model the night sky to determine the position of every star, planet and celestial object above the horizon. Once aligned, the remote hand control allows direct access to each of the celestial catalogs in its user-friendly database.
Celestial Object Database
The CPC database contains over 40,000 celestial objects including Messier objects, the Caldwell Catalog, as well as NGC Galaxies, nebulae and planets. User-definable filter limits make navigating through this expansive database quicker and easier. Filter Limits let you filter out objects that are outside of your local horizon (ie, if trees or mountains were in the way).
Identify feature tells you what you're looking at, but it can also be a very fun way to tour around the sky. Just point the telescope up somewhere and ask it to identify Messier objects (for instance) and it will show you the 5 nearest Messier objects to your position and let you GOTO them. You can keep doing this for different parts of the sky or for different object types -- it is a lot of fun.
There's also "Solar Sys Align" that lets you align on the sun or moon for daytime observing -- it is easy to use this to see planets or bright stars in the day.
The new CPC Series telescopes, like our acclaimed Advanced Series and premium CGE Series telescopes feature meticulously matched and hand-figured optical systems that are manufactured in our facilities in Torrance, California. In addition, all CPC models are available with StarBright and StarBright XLT High Performance Optical Coatings.
With the introduction of the CPC Series, Celestron has “gone back to the drawing board” and re-designed, re-engineered, and re-invented a telescope family that provides superior quality, unsurpassed ease of use, and incomparable value. All CPC models ship standard with our NexRemote telescope control software.

The latest in the evolution of the classic C8 fork mounted telescope that revolutionised amateur astronomy in the UK from the 1970's. The original sand cast manual C8 has evolved into the modern CPC800, with the same 8" f/10 SCT optics, vastly improved optical coatings, a modern fast slewing GOTO system and an on-board GPS unit for automatic time/date/location settings. In standard configuration, the CPC800 is designed to be a fully functioning GOTO telescope in alt-azimuth mode. For imaging purposes an optional Celestron equatorial wedge is required. On a wedge, the telescope is placed into equatorial mode so that tracking requires movement of the RA motor only. The CPC800 is easily portable and is a common sight at star parties. For home use, it is simple to lift the telescope from the house onto a waiting tripod in the back garden. There have been more after-market accessories available from different manufacturers, that are compatible with the C8, than any other telescope. This is because of its historical popularity. This means its adaptability for all aspects of astronomy is backed up by a wealth of Celestron and other manufacturer's accessory products. Compared to the retail price of its predecessors, the modern fork mounted C8 (the CPC800) is lower in price than it has ever been. A modern high-tec complete astronomical telescope is now within the budget of most astronomers.
Requirements. You will need a power supply, either a 12v DC Powertank or 230vAC to 12v DC regulated adapter with tip positive connection to the telescope.
Budget for the Celestron wedge if you would like to attempt video or longer exposure imaging. Also budget for a dew shield, a Neutral density or polarising filter, an f/6.3 Celestron reducer lens and the Baader UHC, OIII and H-beta filters. Also consider a 2" star diagonal for making use of the lower power wide-field 2" eyepieces from Celestron and Skywatcher.With any Cassegrain telescope you will have to consider the affect dew fall. The cheapest solution is a lens hood but when dew is a real problem then heater straps will evaporate dew off.
